Good Morning Ross!
Here is a little something for your presentation, in the event the investors wanted to take the ordering process this far.
This is not as easy as it looks. Notice the reflections in the metal and the leather are reacting to the color of the car itself, as does the pavement. I also changed out the badges on the rims and the nose to match the paint job. There is no "Magic Button" in photoshop that can do this kind of work. I am not going to kid you. This kind of work can get real expensive real quick.
So...
In the perfect world, your customer could pick the color first (standard colors or the two tone) and then pick the color for the leather interior --from actual images. I know we don't have the budget to do this yet, but this might be a good thing to bring up at the meeting for a future ordering system once the cash starts rolling in.
Talk to you soon !
